Welcome to the ATA e-Business Program, where the global commercial aviation industry collaborates to create standards for information exchange to support engineering, maintenance, materiel management and flight operations. For over fifty years, the commercial aviation industry has worked together through a joint international effort to establish specifications for improving business processes and information exchange. Administered and published by the Air Transport Association (ATA) e-Business Program, these international specifications have evolved to meet the changing needs of the industry and to embrace the latest technological advances in information exchange. As a result, the commercial aviation industry has seen dramatic improvements in data efficiency, security and consistency, and has experienced a significant reduction in the time required for delivery and retrieval of operationally critical information.
